Abstract

A three segment fixed chamber baler (3) comprises a fixed segment (14), a tipping segment (15) and a closure segment (17) carrying respective pluralities of bale rotating rollers (25) defining a bale chamber (19) within which crop material is rotated and formed into a cylindrical bale. A pair of double-acting hydraulic rams (40) acting between a chassis (7) of the baler (3) and the closure segment (17) pivots the closure segment (17) between an open state for discharging a bale from the bale chamber (19) and a closed state defining the bale chamber (19). Hydraulic fluid at a selectable hydraulic density pressure is applied to the rams (40) for operating the closure segment (17) between the open and closed state and for urging the closure segment (17) into the closed state during the formation of the bale, so that the bale is formed in the bale chamber (19)to a desired bale density. On the bale being formed to the desired bale density, the bale is circumferentially wrapped in the bale chamber (19). In order to increase the bale density during circumferential wrapping of the bale in the bale chamber (19), the pressure of the hydraulic fluid applied to the rams (40) is cycled between the hydraulic density pressure, and a higher pressure, which is either the baler hydraulic system pressure or the hydraulic system pressure of a tractor at which hydraulic fluid is supplied to the baler (3) during towing thereof by the tractor.
